Alleles at a locus may be dominant or recessive; dominant alleles give rise to their corresponding phenotypes when paired with any other allele for the same trait, whereas recessive alleles give rise to their corresponding phenotype only when paired with another copy of the same allele. For example, if the allele specifying tall stems in pea plants is dominant over the allele specifying short stems, then pea plants that inherit one tall allele from one parent and one short allele from the other parent will also have tall stems. Mendel's work demonstrated that alleles assort independently in the production of gametes, or germ cells, ensuring variation in the next generation. Although Mendelian inheritance remains a good model for many traits determined by single genes (including a number of well-known genetic disorders) it does not include the physical processes of DNA replication and cell division.
Where can alleles be located in order to be either dominant or recessive?
at a locus

A group is called finite if it has a finite number of elements. The number of elements is called the order of the group. An important class is the symmetric groups SN, the groups of permutations of N letters. For example, the symmetric group on 3 letters S3 is the group consisting of all possible orderings of the three letters ABC, i.e. contains the elements ABC, ACB, ..., up to CBA, in total 6 (or 3 factorial) elements. This class is fundamental insofar as any finite group can be expressed as a subgroup of a symmetric group SN for a suitable integer N (Cayley's theorem). Parallel to the group of symmetries of the square above, S3 can also be interpreted as the group of symmetries of an equilateral triangle.
What does a finite group include?
a finite number of elements

The State of the Union Addresses and other presidential speeches are translated to Spanish, following the precedent set by the Bill Clinton administration. Official Spanish translations are available at WhiteHouse.gov. Moreover, non-Hispanic American origin politicians fluent in Spanish-speak in Spanish to Hispanic majority constituencies. There are 500 Spanish newspapers, 152 magazines, and 205 publishers in the United States; magazine and local television advertising expenditures for the Hispanic market have increased much from 1999 to 2003, with growth of 58 percent and 43 percent, respectively.
Was this always the case in American political addresses?

following the precedent set by the Bill Clinton administration. Official Spanish translations are available at WhiteHouse.gov.
